Main contractors
Site carbon, from the bowser to the board report.
Plant fuel, generators, deliveries, waste and subcontractor paperwork arrive from dozens of sources. MetricOra puts them through one review queue and one calculation, per site and per contract.
Where it helps
The jobs that usually end up in a spreadsheet.
Waste tickets arrive on paper from every subcontractor
Drivers and site staff photograph them in the field app. Weight, EWC code, date and vehicle are read on the phone and checked by a reviewer before they count.
Plant diesel and HVO are hard to reconcile
Fuel receipts and bowser deliveries become Scope 1 records. HVO and blends use the library's HVO factor, with biogenic CO₂ reported separately. Telematics feeds show idling and burnt fuel per machine.
Embodied carbon is worked out after the fact
Approving a delivery note can also create an embodied carbon record for the project, from the material's library factor or the supplier's own EPD, with transport to site added.
Clients ask for PAS 2080 and project budgets
Each project can hold a carbon management plan, a reduction opportunity log and a carbon budget with a burn-down against its programme dates.
Per site, per contract
The same numbers for the site team and the head office.
Sites, contracts and programmes sit in one organisation, so a contract's carbon and the group SECR figure come from the same published snapshot.
- Location- and market-based Scope 2 for site supplies and offices
- Spend-based Scope 3 for concrete, steel and services by UK SIC code
- Subcontractors submit evidence without seeing anything else
*Demo data
Review
A reviewer sees exactly what was captured on site.
Recognised values sit beside the submitted ones, so a corrected weight or a mistyped date is obvious before approval.
- Claim a submission so two people do not review it
- Ask the worker for more information without losing the original
- Every decision is written to the audit trail
